Dry Ingredients:1 ½ cups of certified gluten-free old-fashioned rolled oats. Oats provide sustained, slow-releasing energy and are rich in beta-glucan, a soluble fiber that actively lowers cholesterol.1 cup of whole wheat flour or oat flour. This acts as the structural binder, giving the bake its cake-like crumb while adding an extra layer of complex carbohydrates.1 teaspoon of baking powder and ½ teaspoon of baking soda to guarantee a fluffy, towering rise.1 generous tablespoon of ground Ceylon cinnamon and a pinch of freshly grated nutmeg for a warm, comforting sensory aroma that mimics a traditional coffee cake.½ teaspoon of fine sea salt to amplify the natural sweetness of the other ingredients.Wet Ingredients:1 cup of plain, unsweetened whole milk Greek yogurt. This is the secret powerhouse ingredient, adding immense moisture, a tenderizing acidity, and a massive boost of high-quality casein and whey protein.⅓ cup of pure maple syrup. This natural, unrefined sweetener brings essential minerals like manganese and zinc to your morning routine.2 large pasture-raised eggs, brought to room temperature. Eggs act as the crucial emulsifier that holds the matrix of the cake together.¼ cup of melted unrefined coconut oil or unsweetened almond butter. This provides the satiating healthy fats necessary for brain function and hormone regulation.1 teaspoon of pure vanilla extract for floral depth.1 ½ cups of fresh or frozen wild blueberries (or finely diced apples). These burst during baking, creating pockets of jammy, antioxidant-rich sweetness.
